HB TCXX Front Low-Mount Shock Tower Upgrade - Arrowmax AM-TCXX-68763  [AM-TCXX-68763]

Front shock tower with low-mount geometry for HB TCXX

This front shock tower is an aftermarket replacement from Arrowmax, listed under AM-TCXX-68763 and built for HB TCXX models. The low-mount layout is made for the front suspension on HB TCXX chassis and is described here for setup and routine maintenance.

The tower secures the upper ends of the front shocks and defines the shock mounting positions within the front suspension geometry. Moving to a low-mount location changes the shock angle and effective leverage versus taller towers, which alters shock stroke influence and front body roll behaviour at model scale. These changes matter when tuning damping, spring rates or anti-roll settings.

Installation notes: the part is intended for direct fitment to HB TCXX front bulkhead areas that accept low-mount geometry, replacing the stock tower in those locations. When fitting this tower, check shock shaft alignment and confirm full travel is unobstructed through both droop and compression. Minor setup adjustments such as shock length, spring position and anti-roll bar settings may be necessary to regain the handling balance after swapping tower heights.

For hobbyists focused on tuning, treat the tower as one geometric option: it shifts the upper shock eye and therefore the link between suspension travel and damping response. Use this Arrowmax AM-TCXX-68763 tower when you want a lower front shock mounting point on HB TCXX chassis, and always verify fitment before competitive running.
